Gently

She's a lonely girl, a sensitive girl, she needs a gentle stroke.

You place your hands around it and start going back and forth. You can feel that it's still a bit flaccid, maybe her body doesn't have enough blood to get it fully erect? You can feel it responding to your horizontal massage, hardening momentarily, more precum flowing through it in short successions.

Amelia is breathing heavily, trying her best to hold a facade of dignity as a cute boy is stroking her cock. She might had dreamed of finding a man who could tolerate or look past her condition, but never someone willingly engaging it her monstrous cock.
She lean forward in order to touch the top of your head with her finger.

"I feels amazing, thank you very much..." But the self loathing kicked back it "But really, you can stop if y-"

You change your sitting position, right knee on the floor, left knee under the upper half of her cock, you hold the back of the nuzzle with your left hand, stroke the lower half with your right hand.

*mwah*

Amelia feels you kissing her gigantic cock as you stroke harder, she leans back suddenly.

"Haaaaaaa oh my, yes yes yeeeeees gnnn UGH"

You feel a torrent of cum flowing through her cock, surprise makes your right hand lose its grip. You try to hold her cock between your head and your left knee, trying to hold this enormous cock in place. You did right to hold the back of the nozzle, as Amelia's cock is now flooding it, cum forces itself directly into the tube, filling it in seconds. You get your grip back, trying to stabilize the monster. Her orgasm lasts way longer than average, you spend intense seconds holding the nozzle to the tip of her cock, while you can feel her frail body shake frenetically.

Only last burst of cum splits the nozzle in half, leaving a gooey spurt of cold cum in the palm of your hand, splattering your face and torso. The intense sweet smell overwhelms you, it's like you knocked down a whole cream cake on the floor.

You get up, take a look at your guest: she's exhausted, breathing heavily, her monstrous cock spurts its last drop of cum on the carpet, the machine shines with a bright beeping red light, a deformed expression of bliss is plastered on her almost **** face.

You lick the sweet cum off your fingers, taking a certain pride in your work.
